Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange equipment, and in particular to a mine heat exchange equipment and method utilizing mine waste heat. Background Art

[0002] Mine waste heat refers to the waste heat generated during the mining process, which mainly comes from the exhaust air discharged from mine ventilation, mine drainage, and the heat generated by the operation of underground mechanical equipment. These waste heats are usually at a low temperature, but the total amount is considerable. If they can be effectively recycled and utilized, they can not only improve energy utilization efficiency, but also reduce energy waste and environmental pollution. Mine heat exchange equipment is the core device for realizing mine waste heat recovery. Its function is to transfer waste heat to other working fluids or systems through efficient heat exchange technology for heating, power generation or other industrial purposes;

[0003] If the waste heat in mines is not reused, a large amount of thermal energy resources will be wasted. The heat that could have been recycled will be directly discharged into the atmosphere, which will not only aggravate the energy consumption problem, but also cause additional thermal pollution to the environment. At the same time, the temperature inside the mine cannot be effectively regulated, which may lead to an unsuitable working environment temperature, affecting the work efficiency and health of the miners. In addition, failure to fully utilize waste heat resources will also increase mine operating costs because additional energy is required to maintain ventilation and temperature control in the mine.

[0025] The present invention provides a mine heat exchange device and method for utilizing mine waste heat. It has the following beneficial effects:

[0026] 1. The mine heat exchange equipment and method utilizing mine waste heat can realize dynamic circulation of liquid in the inner cavity of the water storage tank through a transfer mechanism during the operation of the equipment, thereby ensuring uniform distribution of liquid temperature. When the liquid temperature in the inner cavity of the water storage tank gradually increases during the heating process and reaches a preset temperature threshold, the transfer mechanism will be automatically triggered to cause the liquid to form a stable flow state, thereby further enhancing the heat exchange efficiency.

[0027] 2. The mine heat exchange equipment and method utilizing mine waste heat, by setting up a heat collection mechanism, can accurately guide and fully utilize the waste heat resources generated in the mine, so that the high-temperature hot air flows along a preset path and fully contacts the outer surface of the water tank and the extended surface of the metal heat absorbing plate.

[0028] 3. The mine heat exchange equipment and method utilizing waste heat from the mine, by setting a heat dissipation device, can, under the coordinated action of the transfer mechanism, directionally transport the heated water flow in the inner cavity of the water storage tank to the target area that needs to be heated in the mine. In this process, the heated water flow is fully in contact with the cold air in the mine through the heat exchange device, and gradually releases heat energy, thereby achieving uniform heating of the mine air. This circulating heating method can not only stably increase the ambient temperature in the mine, but also effectively improve the working conditions of the mine, and ultimately efficiently complete the task of increasing the temperature of the mine.

[0029] 4. The mine heat exchange equipment and method utilizing mine waste heat can monitor the temperature changes of the liquid in the inner cavity of the water tank in real time through the precise regulation of the water temperature control mechanism. When the temperature of the liquid gradually rises during the heating process and reaches the preset threshold, the water temperature control mechanism will respond immediately and automatically start the discharge mechanism to safely and efficiently discharge the heated liquid from the inner cavity of the water tank. This process not only ensures the accuracy of temperature control, but also avoids overheating or energy waste, thereby realizing the intelligent and efficient operation of the system.

[0047] The metal heat absorbing sheet 4 is used to absorb the waste heat of the mine and transfer it to the water storage tank 3. The metal heat absorbing sheet 4 is fixedly connected to the water storage tank 3. The metal heat absorbing sheet 4 is made of metal material and can absorb the heat in the air and transfer it to the inner cavity of the water storage tank 3, so that the heat can be transferred from a high temperature place to a low temperature place, and finally the water flow in the inner cavity of the water storage tank 3 is heated;

[0049] The heat collecting mechanism 6 is used to transfer the waste heat in the mine to the outer surface of the water storage tank 3. By setting the heat collecting mechanism 6, the waste heat in the mine can be guided so that the hot gas can contact the outer surface of the water storage tank 3 and the outer surface of the metal heat absorbing sheet 4, and then the heat can flow into the liquid in the inner cavity of the water storage tank 3;

[0050] The heat dissipation device 7 is used to transfer the heat in the water flow to the mine. By setting the heat dissipation device 7, the water flow heated in the inner cavity of the water storage tank 3 can be discharged to the mine area that needs to be heated under the action of the transfer mechanism 5, and finally the air in the mine is heated by heat exchange, and finally the temperature increase work of the mine is completed;

The bottom end of the partition rod 93 is fixedly connected to a limit tube 94. The inner cavity of the limit tube 94 is slidably connected to a piston 95. The lower surface of the piston 95 is fixedly connected to a connecting rod 96. The bottom end of the connecting rod 96 is fixedly connected to a brush plate 97. The brush plate 97 is fixedly connected to the metal heat absorbing plate 4. The heat absorbing plate 4 is frictionally adapted. By setting a spacer rod 93, a gap can be generated between the limiting tube 94 and the fixed tube 92, so that when the piston 95 leaves the area of ​​the limiting rod 93, the air in the inner cavity of the limiting tube 94 can circulate with the outside. By setting the limiting tube 94, the piston 95 can be limited so that the piston 95 can move up and down in the inner cavity of the limiting tube 94.

[0054] The transfer mechanism 5 includes a water inlet pipe 51 and a first connecting pipe 52, the water inlet pipe 51 passes through the upper surface of the shell 1, the first connecting pipe 52 passes through the bottom surface of the inner cavity of the shell 1, the bottom end of the first connecting pipe 52 passes through the water storage tank 3, the water inlet pipe 51 is located directly above the first connecting pipe 52, a sealing frame 53 is fixedly connected to the inner wall of the first connecting pipe 52, a first cylindrical coil spring 54 is fixedly connected to the top surface of the inner cavity of the sealing frame 53, a first fixing rod 55 is fixedly connected to the bottom end of the first cylindrical coil spring 54, a first baffle plate 56 is fixedly connected to the end of the first fixing rod 55, and the first baffle plate 56 The first connecting pipe 52 and the first cylindrical coil spring 54 are provided to continuously press the first blocking plate 56 to prevent the first cylindrical coil spring 54 from being pressed against the first blocking plate 56. It always fits tightly to the sealing frame 53 in the absence of liquid impact and maintains a sealed state, thereby effectively preventing liquid leakage or backflow and ensuring the stability and reliability of system operation. The transfer mechanism 5 also includes a water pump 57 and a water temperature control mechanism 58. The water pump 57 passes through the top surface of the inner cavity of the shell 1. The water temperature control mechanism 58 includes a second connecting pipe 581, which passes through the bottom surface of the inner cavity of the shell 1.

In addition, by arranging the sealing box 584 and the sealing ring 585, a closed space is formed with the inner wall of the second connecting pipe 581. When the temperature of the liquid in the inner cavity of the water storage tank 3 increases, the air in the inner cavity of the sealing box 584 expands due to the principle of thermal expansion and contraction, pushing the sealing ring 585 to move upward, and at the second fixing rod 586 Driven by the movement of the moving circle 587, the moving circle 587 is caused to move upward synchronously. This series of linkage designs not only realizes the accuracy and automation of temperature control, but also ensures the efficiency and stability of system operation.

By providing the connecting frame 589 and the second blocking plate 5810, when the moving circle 587 moves upward, the second blocking plate 5810 can no longer block the opening of the blocking box 582, and then the liquid in the inner cavity of the water storage tank 3 can be discharged through the second connecting tube 581 under the suction force generated by the water pump 57.

By setting a stepper motor 652, after the power is connected and the switch is turned on, the rotating column 653 can drive the fan blade 654 to rotate, thereby generating an airflow, so that the geothermal heat in the medium-deep mine can be blown to the outer surface of the water storage tank 3. By setting the circular gear 655, when the rotating column 653 rotates, it can mesh with the rack 610, thereby generating lateral movement in the inner cavity of the support frame 63. By setting the inclined plate 611 and the spacer 612, after the circular gear 655 moves to the end of the rack 610, the circular gear 655 can move to the The package box 651 moves downward and is located below the partition bar 612. The circular gear 655 is meshed with the rack 610. The outer side surface of the package box 651 is fixedly connected with a fixed block 656. The outer surface of the fixed block 656 is fixedly connected with a sliding frame 657. The inner cavity of the sliding frame 657 is slidably connected with a track frame 6511. The lower surface of the sliding frame 657 is fixedly connected with a second cylindrical coil spring 658. The bottom end of the second cylindrical coil spring 658 is fixedly connected to the surface of the track frame 6511. The outer surface of the track frame 6511 is fixedly connected with a moving ring 659. The moving ring 659 is slidably connected to the outer surface of the track rod 69. The outer surface of the moving ring 659 is fixedly connected with a third cylindrical coil spring 651 0. By setting the sliding frame 657, it can cooperate with the track frame 6511, so that the positions of the fixed block 656 and the moving ring 659 can change vertically. By setting the second cylindrical coil spring 658, an upward squeezing force can be always applied to the sliding frame 657 to ensure that the sliding frame 657 maintains a stable reset ability during movement. At the same time, by configuring the third cylindrical coil spring 6510, after the moving ring 659 completes the lateral movement, it can be subjected to the tension and quickly rebound to the initial position.

[0056] The heat dissipation device 7 includes an insulation pipe 71, and the number of the insulation pipes 71 is two. The two insulation pipes 71 are fixedly connected to the upper surfaces of the water pump 57 and the water inlet pipe 51 respectively. The insulation pipe 71 includes a rubber inner layer 713, and the outer surface of the rubber inner layer 713 is fixedly connected to an insulation layer 712, and the outer surface of the insulation layer 712 is sleeved with a rubber outer layer 711. The length of the insulation pipe 71 changes according to the distance between the waste heat of the mine and the mine to be heated. By setting the insulation pipe 71, the temperature of the liquid can be insulated to prevent a large amount of temperature loss when the liquid is circulated. The top of the insulation pipe 71 is fixedly connected to a first connecting pipe 72, and the top of the first connecting pipe 72 is fixedly connected to a first connecting box 73. The outer surface of the first connecting box 73 is fixedly connected to A metal heat dissipation pipe 74 is connected, and the end of the metal heat dissipation pipe 74 is fixedly connected to a second connecting box 75, and the outer surface of the second connecting box 75 is fixedly connected to a second connecting pipe 76, and the second connecting pipe 76 is fixedly connected to the top of the insulation pipe 71. By setting the metal heat dissipation pipe 74, the heat carried in the liquid can be quickly dissipated to the surrounding environment through the outer surface of the metal heat dissipation pipe 74, thereby effectively improving the temperature in the mine. At the same time, by configuring the second connecting box 75 and the second connecting pipe 76, the water flow after the heat exchange in the inner cavity of the metal heat dissipation pipe 74 can be redirected back to the inner cavity of the water storage tank 3 to form a closed loop. This design not only realizes the efficient transfer of heat and the stable increase of the mine temperature, but also ensures the recycling of water resources, thereby improving the overall energy efficiency and sustainability of the system.

[0057] A temperature increasing method comprises the following steps:

[0058] Step 1: Accurately detect the temperature distribution in the deep area of ​​the mine and locate the area with the highest temperature. Then, firmly place the housing 1 in the high temperature area and firmly fix it with expansion screws to ensure the stability of the equipment. At the same time, place the metal heat dissipation pipe 74 in the target area that needs to be heated in the mine to prepare for subsequent heat transfer.

[0059] Step 2: Inject water into the inner cavity of the water tank 3, start the water pump 57, and make the water circulate in the inner cavity of the water tank 3. Then, start the stepper motor 652 to drive the rotating column 653 to drive the fan blades 654 and the circular gear 655 to rotate, thereby generating a strong airflow to provide power support for the heat transfer.

[0060] Step three: The high-temperature air deep in the mine flows to the metal heat-absorbing sheet 4 under the blowing of the fan blades 654, and transfers the heat to the inner cavity of the water tank 3. As the water temperature in the inner cavity of the water tank 3 gradually increases, the gas in the inner cavity of the sealing box 584 expands due to the heat, pushing the sealing ring 585 and the moving ring 587 to move upward, and finally the heated water flows into the inner cavity of the metal heat dissipation pipe 74 through the water pump 57. The heat is quickly dissipated into the mine environment through the outer surface of the metal heat dissipation pipe 74, thereby achieving uniform heating of the mine and improving the temperature conditions in the mine.

[0061] Working principle: When in use, the operator detects the temperature of the middle and deep layers of the mine and detects the area with the highest temperature. Then, the shell 1 is placed in the area with the highest temperature in the middle and deep layers of the mine, and is fixed with expansion screws, and the metal heat dissipation pipe 74 is placed in the area that needs to be heated; then the operator connects the stepper motor 652 to the power supply and turns on the switch, so that the rotating column 653 drives the fan blades 654 and the circular gear 655 to rotate, thereby blowing the hot air to the outer surface of the water tank 3. At the same time, the circular gear 655 is engaged with the rack 610, so that the stepper motor 652 is subjected to a lateral force and produces a lateral movement. After moving to the end of the rack 610, under the action of the inclined plate 611, the circular gear 655 is located below the partition bar 612, and then under the pulling force of the third cylindrical coil spring 6510, the moving ring 659 returns to its original position and restarts the circulation work, so that the hot air is evenly blown to the outer surface of the water tank 3; after the temperature of the liquid in the inner cavity of the water tank 3 rises, the sealing box 5 The air in the inner cavity of 84 will expand due to the principle of thermal expansion and contraction, thereby causing the sealing ring 585 to move upward, and then driven by the second fixed rod 586, the moving circle 587 to move upward. When the moving circle 587 moves upward, the second blocking plate 5810 no longer blocks the opening of the blocking box 582, and then under the suction generated by the water pump 57, the liquid in the inner cavity of the water storage tank 3 can be discharged through the second connecting pipe 581. In the process of the moving circle 587 moving upward, the top ring 5811 is squeezed with the lower surface of the blocking box 582, thereby compressing the air in the inner cavity of the first elastic tube 588 and then discharging it from the hole at the bottom, and the second elastic tube 5812 is stretched and the water pipe 5813 is inserted into the liquid, so that the water pump 57 can suck out the water flow; the liquid with higher temperature enters the inner cavity of the metal heat dissipation pipe 74 through the insulation pipe 71, the first connecting pipe 72 and the first connecting box 73, and under the principle of fast metal heat dissipation, the air in the mine is heated.
